Abstract
A semiconductor device includes a substrate, first and second fins over the substrate and extending upwardly in a first direction, an epitaxial material comprising a first portion, a second portion, and a third portion, and a conductive feature in contact with the epitaxial material. The first portion is located on the first fin, the second portion is located on the second fin, and the third portion is connected to the first and second portions. The third portion has a bottom surface bended upwardly with an apex located between the first and second fins. In a cross-sectional plane perpendicular to a lengthwise direction of the first and second fins, the bottom surface has a first straight line and a second straight line intersecting at the apex.
